Abstract: When incubated with a creosote-polycyclic aromatic hydrocarbons (PAHs) mixture, the pyrene-degrading strain Mycobacterium sp. AP1 acted on three- and four-ring components, causing the simultaneous depletion of 25% of the total PAHs in 30 days. The kinetics of disappearance of individual PAHs was consistent with differences in aqueous solubility. During the incubation, a number of acid metabolites indicative of distinctive reactions carried out by high-molecular-weight PAH-degrading mycobacteria accumulated in the medium. Most of these metabolites were dicarboxylic aromatic acids formed as a result of the utilization of growth substrates (phenanthrene, pyrene, or fluoranthene) by multibranched pathways including meta- and ortho-ring-cleavage reactions: phthalic acid, naphthalene-1,8-dicarboxylic acid, phenanthrene-4,5-dicarboxylic acid, diphenic acid, Z-9-carboxymethylenefluorene-1-carboxylic acid, and 6,6?-dihydroxy-2,2?-biphenyl dicarboxylic acid. Others were dead-end products resulting from cometabolic oxidations on nongrowth substrates (fluorene meta-cleavage product). These results contribute to the general knowledge of the biochemical processes that determine the fate of the individual components of PAH mixtures in polluted soils. The identification of the partially oxidized compounds will facilitate to develop analytical methods to determine their potential formation and accumulation in contaminated sites.

This depression does not constitute a symmetric graben with steep master faults but rather a complex transition zone. Blocks detached from the granitic sierras are downfaulted and tilted to the northeast along the frong of these sierras. Farther to the north, the granitic basement deepens gradually. However, it steepens at the limit between the Sierra Madre Occidental and the Jalisco Block. Northwest of our study area, the limit is located north of the Plan de Barrancas fault. At the east the limit is located closer to the southward prolongation of the Plan de Barrancas fault. The change in position occurs near La Primavera caldera. The La Primavera caldera, Tequila volcano, and vents of cinder and lava cones are emplaced along NW-SE weakness zones in the batholith. The crust of the Sierra Madre Occidental adjacent to the limit features NE-SW lineaments perpendicular to those of the neighbouring Jalisco Block (JB).",,,,,,,,,"http://hdl.handle.net/20.500.12104/44517","http://www.scopus.com/inward/record.url?eid=2-s2.0-18244431342&partnerID=40&md5=c0b5c17df92ee1c3627f249d74c4cc54",,,,,,"4",,"Geofisica Internacional",,"263

Absolute volume of alcohol consumption was not different between sexes in any condition; however, females consumed significantly more alcohol than males on a g/kg basis in all conditions. These differences were significantly more extensive during continuous free- choice to alcohol and water than during forced alcohol consumption. Females showed greater alcohol preference than males only during continuous free- choice to alcohol and water. During periodic free-choice to alcohol and water condition, alcohol consumption was distributed during more hours throughout the day in females than males. During periodic free-choice to alcohol and to an isocaloric sweetened solution (ISS), intakes of ISS were very high compared to regular intakes of daily water; nevertheless, alcohol consumption was maintained to similar levels observed in continuous free-choice to alcohol and water and represented almost 50% of regular daily consumes of water in males and females. Free-choice for alcohol and ISS modified the usual pattern of alcohol consumption during the daily light-dark cycle in males and females and reduced the time devoted to drinking alcohol compared to other conditions, in which similar intakes were observed. Results show that the extent of the higher alcohol consumption in females than males and the changes in patterns of alcohol intake were dependent on the nature of the ingestion schedule.",,,,,,"10.1016/S0741-8329(99)00010-5",,,"http://hdl.handle.net/20.500.12104/44506","http://www.scopus.com/inward/record.url?eid=2-s2.0-0344994562&partnerID=40&md5=2aa95e2e4b418414ea9fb6c9e254fd80",,,,,,"1",,"Alcohol",,"15

Therefore, the objective of this work was to provide further information about the sexual behavior of this species in intensive production systems. Fourteen 6- to 12-month-old rabbits were studied for 6 months (July/December) when housed individually under natural photoperiod (19 degrees latitude north). They were mated once a week. When mated they were exposed at 6-min intervals to five oestrous females. The number of mounts, time between mounts, time and number of ejaculations, time between ejaculations, and also enuresis, grasping and kicking were recorded. Mounts (n=222) were observed and recorded. Males mated one to five times during each evaluative session. Enuresis was present only in one observation. Sexual aggressiveness such as grasping and kicking was present during 142 and 133 matings. Time for mounting and ejaculation in accumulated means (minutes, seconds, tenths) from the first to the fifth mount were noted and an accumulative average of 4.20 min for the fifth mounting was noted. Minimum times for ejaculation and next mating was 00:17:00 min and maximum was 05:33:03 min. It was concluded that sexual behavior in white New Zealand male rabbits remained unchanged through the duration of the period of study.",,,,,,,,,"http://hdl.handle.net/20.500.12104/44512","http://www.scopus.com/inward/record.url?eid=2-s2.0-2142756849&partnerID=40&md5=a10c8c4061086962f2cebd5009bc5fb1

Our results indicate that, for molar ratios of salt to surfactant (CSALT/CDTAB) smaller than 1, the micellar solutions follow closely Maxwell behavior with a single relaxation time, that is, they are in the fast-breaking regime, and exhibit shear banding above a critical shear rate. When this ratio is greater than 1, micellar solutions behave as semidilute polymer solutions with a spectrum of relaxation times and no stress plateau is observed in steady shear. The results are analyzed with the Granek-Cates model (for linear response) and with a simple model that consists of the upper convected Maxwell constitutive equation coupled to a kinetic equation to account for the breaking and reformation of the micelles (nonlinear behavior). The stress plateau and the critical shear rates are determined from an extended irreversible thermodynamic analysis.",,,,,,"10.1021/la034052o",,,"http://hdl.handle.net/20.500.12104/44522","http://www.scopus.com/inward/record.url?eid=2-s2.0-0041387422&partnerID=40&md5=37bc4089e17c72966ee031a97fe381ba

The field of nanomedicine is concerned with technology based on the development of materials at the nanometric scale. In this paper, apoptosis/proliferation and lipid peroxide activity were evaluated in L5178Y lymphoma cells after exposure of Ag nanoparticles (NPs) to different concentrations of nanomaterials. Ag-NPs showed absorption at 412 nm, with a diameter of 2 9 nm. The treatment of L5178Y lymphoma cells with Ag-NPs demonstrated a significant decrement in the cellular proliferation index at 9 ?g/mL; this result was supported with apoptosis determination, because at higher concentrations (>9 ?g/mL) of Ag-NPs we observed the maximum peaks. With regard to the apoptotic mechanism of the effects of Ag-NPs on cell viability, we evaluated the lipoperoxide activity, which showed an important increment at the same concentration of Ag-NPs (9 18 ?g/mL). We demonstrated that L5178Y lymphoma cells showed apoptosis induced by treatment with Ag-NPs; the possible mechanism of this effect could be the generation of lipoperoxides. Our study provides evidence for a molecular mechanism of Ag-NP-induced generation of reactive oxygen species (ROS). " 2014 Inst Materials Physicss. All rights reserved.
